METHOD OF MAKING- A DIE.

Specification of Letters Patent.

Patented Nov. 22, 1921.

Application filed April 29, 1919, Serial No. 293,527. Renewed October11, 1921. Serial No. 507,158.

To all whom it may concern Be it known that I, ALBERT A. MOINTYRE,

a citizen of the United States, residing at Bonners Ferry, in the countyof Boundary and State of Idaho, have invented new and usefulImprovements in Methods of Making a Die, of which the following is aspecification.

The object of this invention is to provide a device for the syntheticand analytic study of a complete entityby segregation and combination ofthe partsof such entity.

In the more specific form of my invention the same is applied to thestudy of geography, and will be so illustrated, the device presenting,when united, an integral or complete political entity which issub-divided so that it can be segregated into predetermined and definiteintegers.

More specifically speaking, my invention has to do with an improvedmethod whereby a previously printed and completed map,

for instance, may be subsequently severed or sub-divided into itsvarious counties, if the map is of a State, or into its componentStates, if the map is of a country. In this connection, sub-divided mapshave heretofore been made at great expense owing to the necessity forindividual hand work in their production, as regards the severance ofthe entity into its integers.

In accordance with my improved method, an imprint of the exactconfiguration of the map or entity is made upon a block of which animproved die is afterward made. This block is sub-divided on the exactlines of the configuration impressed thereon, and in the kerfs of thesaw or other sub-dividing tool are disposed cutting ruling means. Thecutting ruling means project in relief from that face of the block ordie which presents the configuration in the negative form. Therefore,when this cutting die is brought into sub-dividing impression engagementwith the previously printed map, in positive facing relation toward thedie, the die will sever the map into its component integers precisely onthe lines of configuration division of the map. Thus, by a mechanicaland rapid method I am enabled to very rapidly and accurately producesub-dividedentities which heretofore have been altogether too costly toin any way figure as a large and cheap volume product.

As'a mechanism, my invention comprises is cutting die having impressedon one. face thereof the configuration of the finished printed matter tobe sub-divided, the die being severed on the lines of the configurationand having cutting ruling means interposed in the kerfs of the saw orother severing implement.

My invention has other features and objects which will be more fullydescribed in connection with the accompanying drawings and which will bemore particularly pointed out in and by the appendedclaims.

In the drawings Figure 1 is a face view of an engraved plate, innegative, on which the configuration of the map appears, itbeing assumedthat this plate is on the bed of a platen press..

Fig. 2 is a contracted view of a tympan on in Fig. 1.

Fig. 5 is a face view of the block after it has been sub-divided andequipped with its cutting rule means and clamped in a chase.

Fig. 6 is a sectional view on line 6-6 of Fig. 5.

Fig. 7 product.

Fig. .8 is an edge view thereof.

Like characters of reference designate similar parts throughout-thedifferent figures of the drawings.

My improved method may be carried out in at least two different ways.The engraved plate 1, having on its face the configuration of the map tobe printed, as indicated at 2, may be secured to the bed of a platenpress. A tympan 3, on the platen,

is a face view of the sub-divided the plate 1. Preferably, two or threeimpressions will be made on the tympan not only'for the purpose ofgetting a clear and continuous line impression but also for the purposeof getting enough ink on the tympan to makean unbroken offset impressiontherefrom. The plate is then removed from the may serve to take an inkedimpression from bed and an integral wood or like block 4 is was r the a@fiset er save is then transferred from the tympan to the woodblock 4:,as indicated by the lines in Fig. 3. Now it will be seen that the nega-.

tive impression from the plate 1 will have been transferred to thetympan, in positive form, and the offset impression will have beentransferred back to the block in negative form. T he block 4: is thensevered on lines 2 thereby sub-dividing the same into counties indicatedby lines 2. Instead of giving the counties names, I will represent H@779 C b 77,, 0 777 (C d 77, C e 797 (4 ;77,' 4C 77 i V The hack-saw orother implement used to sub-divide the: block t will leave a horrorkerfs, as clearly indicated" at 5,.in"th'e-finished product, these kerffaces being unnecessary to illustrate-in Fig. 4. Iinterp'ose in thesekerfs ruling elements 6, similar-elements 7 bordering the edges of theblock. These ruling elements or strips may either be bent initially tofit the configuration of the lrerfs, or,-when the sub-divided block isclamped in the chase 6, the elements be shaped to form. However, in anyevent,

the ruling elements or membersare necessarily made of thin metal whichcan readily be shaped to the necessary form and I do not wish to belimited to any specific man-;

ner of so doing although I consider it a novel feature to shape theseruling elements,

broadly. These ruling elements are prefer ablyo'f a width slightly'inexcess of the thickness of the block so that their edges 8 will projectin relief from'one'faceof the block. These projecting edges aresharpened.

to form kniteor'cutting edges as will be clearly seen by'reierencetoFig; 6. Now it will be clear that as far as the block is con cerned itdoes not make any difference on which face thereof the printedimpression is made. In any event, when the block is in use forsub-dividing previously printed maps, in positive, that face or theblock which will be considered face 9 will be presented to the entitytorbe sub-divided, and face 9 will present the configuration in negativeform. Therefore while'the ink impression or transfer mighthave' beenmade on face 10 of the block, it will be a simple matter todispose theruling elements so 7 ct 1nre list from the opposite race.

If desired, a direct impression from plate 1 may be made on the block,in thefirst in-- stance, by fixing the block on the platen of the press.Either way, is clearly within the purvlew of my invention.

Taking a simple method o1 describing the operation, it will beassumed'that the plate 1 is disposed on the; bed of a platen press andthat a number of the desired quantityof cards 11 haye been printedwiththe map as-engraved onthe-plate; Thus is" will be assumed that one"thousand" ma'pfi cards 11 Either before or after this printingoperation, my improved die will have been made up and clamped into achase, as shown in Fig. 5. the platel is taken out of the press and thestructure shown in 5 is substituted, therefor on the bed. These printedcards are then taken one by one, in the usual manher, and fed into placeon the gages of the platen. the press operates, the cutting ruling edgesof the die will. be brought into impression engagement with the printedcards and will subdivide them as indicated at 5. The cutting edgesof theruling elements will necessarily register accurately with the lines onthe previously printed map by reas'onot the fact that the guiding linesof severance for subdividing the block constituted theimpres'sion fromthe very plate which printed the maps. Now if the cards ll werecompletely subdivided, considerable difiiculty would be encountered inremoving the integers from the platen. Therefore, certainof the cuttingedges of the rule'ele ments are interrupted, as indicated at 12, in Fig.6. By this means, the integers of the" map will be completelyseveredexcept for those minute junctures formed or left by the slightinterruptions 12. Thus the substantially completely subdividedintegers'can be bodily removed from the platen with the same facility asthe'integral card was inserte'd thereon. r r V w In some instances. thecard when'being printed will be slightly larger, relatively speaking,than that shown in Fig. 3, in which event the bordering cutting rules?would cut the edges of thecard'to size. By means of the device andmethod in vention herein disclosed I have proven that After thecards'have dried, then s.

integers or complete entity may be segre- V eneral public at a very ingnature in the putting'together and talr in'g apart of the subdividedintegers. V

It is believed that the novelty and utility of my invention will befully understoodfromthe foregoing description, and while I have hereinshown and described different species of the genus, I do not; wish to belimited theretoexcept for such limitations asthe claimsm'ayimport; v r

I claim- 1. The herein-described method of making a die for thesubdivision of integers of an entity, Which consists, in making on a diestock or block an impression from the engraved or other printing platein exact facsimile of the configuration of the entity and its integersto be printed, in subdividing the block on the lines of suchconfiguration, and in interposing cutting rules in suchlines of divisionof the block With the cutting edges of said rules in relief from thecutting or impression side of the block.

2. The herein-described method of making a die for subdividing theintegers of an entity, which consists, in transferring upon a die blocka line impression of such entity, in subdividing the block into integerson the lines of such impression, in interposing cuttingrules in thelines of such subdivision, and in applying pressure to the divided blockintegers to shape the rules to said lines of division. s In testimonythat I claim the foregoing as my own, I hereby afiix my signature.ALBERT A.
